BENJAMIN F. ADAMS, OF BROOKLYN, NEW YORK.

REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 271,391, dated January30, 183,

Application filed July 24, 1882. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN F. ADAMS, a citizen of the United States,residing in the city of Brooklyn, in the county of Kings and State ofNew York, have invented certain new and useful Improvements inRefrigerators;

and I'do hereby declare that the following is a full. clear, and exactdescription of the same.

The object of my invention is to produce an ice-box or refrigeratorwhich will utilize both the ice and the ice-water caused by the meltingof the ice for cooling and condensing purposes, so thata low degree oftemperature may be obtained and the air in the refrigerator be kept dryat the same time.

My invention consists essentially in an inner lining formed intocorrugations and arranged on two or more sides of the interior portionof the box, and the combination therewith of anice'chamber at the top ofthe box, having its floor of a single thickness of metal, inclined inopposite directions at suitable angles to cause the water from themelting ice on the upper side and the moisture produced by condensationon the lower side of said floor to pass to the outer side of saidcorrugated lining without dropping into the body of the box and withoutthe aid of an extra piece of metal or covering.

The accompanying drawings illustrate amode of carrying out my invention.

Figure lis avertical sectional view, looking toward the front of arefrigerator provided with myimproved lining and ice-chamber. Fig. 2 isa vertical section taken in the line 00 0c of Fig. 1. Fig. 3 isahorizontal section taken in the'line y y of Fig. 1. Fig. 4 is ahorizontal section taken in the line z z of Fig. 1. Fig. 5 is a detailview.

The outer casing,A, may be of wood or any other suitable material, andthe metal lining,

' B may be attached thereto in the usual or any suitable manner. Theice-chamberG is at the top of the box, and is formed by the lid andsides of the box and by a plate, E, constituting the floor of thechamber. This plate or floor E is formed of a single thickness of metal,the object of which is to have a surface in the upper part of the boxthat will always be as cold as the ice which lies on the top of it,thereby distributing cold air from the most advantageous part of thebox-namely, the topand allowing it to fall through the entire innerportion to the bottom of the box. The plate or floor E is inclineddownward in opposite directions at a suitable angle-say about forty-fivedegrees-to enable it to carry off the drippings from the melting ice onthe upper surface and the moisture of condensation on the lowersurfaceyand deposit the same on the outer surface of the corrugatedinner lining. The object in having said floor inclined at so great anangle is to carry the moisture of condensation along the under surfaceto the outer side of the corrugated lining without the aid of anotherpiece of metal or covering for the purpose of catching the drippingmoisture, which extra covering would keep the cold air from passing downthrough the inner portion or body of the box. If the corrugated liningis applied to only two sides of the box, the floor E is inclined in onlytwo opposite directions, as shown in Fig. l; butif the corrugated liningis applied to all four sides of the box the floor E is inclined in suchdirections as to communicate with all four of said sides.

The inner lining, G, may be formed in a single piece on each of thesides to which it is applied,as shown in Figs. 1 and 2; or it may beformed of slats or strips, as shown in Fig. 5, in which latter case theslats or strips may be arranged to touch each other or to drip one uponanother, as may be preferred. In either case the corrugations or slatsare so arranged that the drippings and moisture of condensation may bedistributed evenly and uniformly over the entire surface of the innerlining, and pass slowly down until they reach the bottom of the box,upon which they drop from the lower edge of the lining, and areconducted by a gutter, h, to an escape-pipe, z, leading from saidbottom. This can be accomplished by having the corrugations eitherhorizontal or inclined in zigzag form. The object in having the innerlining corrugated and placed in such a position as to receive thedrippings from the ice-chamber at the top is to cause the ice-water fromthe ice-chamber and the moisture from the under surface of the floor toflow slowly back and forth over the corrugated surface until it reachesthe bottom of ICO the box, which process will extract from the ice, thewater, and the moisture of condensation a'll the cold which is of anyvalue.

hen an extremely low temperature is desired-as, for exam ple, forpreserving ice-cream or for similar purposesthe space between the liningB and inner lining, Gr, may, if desired, be packed with fine ice andsalt.

This invention may be readily applied to ice-houses and refrigeratingcars, barges, or vessels of any description.

What I claim as new, and desire to secure by Letters Patent, is-

In a refrigerator, an auxiliary lining for the food-chamber, consistingof corrugated plates separated by space from the walls of said chamber,and adapted to receive at their upper outside surface the waste waterfrom the upper and lower surfaces of a superimposed ice'chamber, and toconduct the same through the space between said auxiliarylining and thewalls of the refrigerator, substantially as described.

2. In a refrigerator, the icechamber 0, consisting of the walls A andthe sloping floor E, adapted to form a roof or top to the food-chamber,in combination with horizontally-corrugated plates or strips G, locatedat one or more sides of the food-chamber, and adapted to receive attheir upper outside surfaces the waste water from the sloping top, andto conduct the same to suitable collecting-gutter in the floor or bottomof said food-chamber, substantially as shown and described.
